What the formula actually does
Each row says where it comes from: F means we derived it from this product’s own ingredient list, S means it is a claim the brand makes that the formula neither confirms nor contradicts.
The brand states a protection temperature — a label claim, not a measurement.
Middle of the range — noticeable on fine hair, light on coarse hair.
Some slip, mostly from esters or silicones rather than conditioners.
Nothing here needs a detergent wash to remove.
No humectants found — nothing here pulls water into the hair.
Fast-drying alcohol in the first three ingredients.
Fragrance is listed; it sits below the working ingredients.
Ingredients that matter
The workhorse ingredients plus anything lower down that changes a decision. These chips name what an ingredient does — they are not safety scores, and no ingredient here is rated good or bad on its own.

US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.
A non-flammable aerosol propellant used in dry shampoos and finishing sprays.
Listed in the first three ingredients, it is likely a structural part of this formula.
Fast-drying alcohol used to make sprays set quickly. In leave-on products it can leave hair feeling dry, especially in high position on the list.
Listed in the first three ingredients, it is likely a structural part of this formula.
Evaporates on contact, which is how a spray sets almost instantly and leaves no weight behind it.
Porous hair gives water up easily as it is; a fast-evaporating solvent high on the list accelerates that.
It evaporates quickly and takes some water with it. On hair already short of moisture, a formula built on a lot of it can finish drier than it started.
A light, quickly evaporating carrier that spreads silicones and oils thinly, then leaves.
Listed in the first three ingredients, it is likely a structural part of this formula.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
A fast-evaporating carrier that lets oils and polymers spread thinly, then leaves nothing behind.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
A solubiliser that keeps oils and fragrance dissolved in clear liquids.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A light ester used for fast spreading and a non-greasy finish.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A light emollient: it softens the surface with noticeably less weight than an oil or a butter.
Spreads thin and lowers friction between strands without the heaviness of a fixed oil.
A light ester used for shine and slip in finishing products.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A light emollient: it softens the surface with noticeably less weight than an oil or a butter.
Spreads thin and lowers friction between strands without the heaviness of a fixed oil.
Argan oil. A medium-weight oil used for shine and softness on the outside of the strand.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.
A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.
Near the top of a list an oil is weight before it is anything else, and fine hair shows that first at the roots.
A light, widely used oil that softens without much weight.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.
A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.
It works on the surface. In the comparison that established coconut oil's penetration, sunflower oil did not reduce protein loss from washing — its fatty acids are bulkier and less linear. It softens and smooths; it does not reinforce the fibre.
The fully hydrogenated form of squalene, now made from olive or sugarcane rather than shark liver. Hydrogenation is what makes it so slow to oxidise; it spreads very lightly and absorbs without a greasy film.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
A light macadamia-derived ester used for a dry, silky finish.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
A light emollient: it softens the surface with noticeably less weight than an oil or a butter.
Spreads thin and lowers friction between strands without the heaviness of a fixed oil.
A liquid fatty alcohol that adds slip and helps other oils spread.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
The waxy solid that gives a conditioner its body. It deposits a soft lubricating layer, which is most of what makes hair feel smooth after rinsing.
Deposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.
A fatty ester. Esters give slip and a smooth after-feel; lighter ones read dry and silky, heavier ones read rich.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
A light emollient: it softens the surface with noticeably less weight than an oil or a butter.
Spreads thin and lowers friction between strands without the heaviness of a fixed oil.
A plant-derived light alkane used as a clean-feeling replacement for silicone or mineral oil.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
A UV filter added to protect the product's colour and, in leave-ins, to slow colour fade.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Sunlight oxidises hair pigment, and on gray, silver or lightened hair that shows up as yellowing. A UV filter on the label absorbs some of the light that drives it.
An apple-derived acid used to bring the formula to an acidic pH.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
pH adjusters are how a formula is brought to a chosen acidity, and an acidic formula keeps the cuticle lying flatter than an alkaline one. Which way this one moves the pH depends on the formula, and the finished pH is not on the label.
An undisclosed blend of scent ingredients. Regulations let it stay unlisted, so a fragrance-free product is the only way to be certain what is not in it.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.
A fragrance component with a faint balsamic scent, named separately on the label because it is a recognised contact allergen.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
One of the 26 scent components the EU requires to be named individually above a threshold. It is named because it is a known contact allergen, not because it is unusual.
A synthetic musk or woody-amber note used as a fragrance base.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.
A violet-like fragrance component named separately as a recognised allergen.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
One of the 26 scent components the EU requires to be named individually above a threshold. It is named because it is a known contact allergen, not because it is unusual.
A lavender-like fragrance component, related to linalool and listed for the same allergen reason.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
One of the 26 scent components the EU requires to be named individually above a threshold. It is named because it is a known contact allergen, not because it is unusual.
The main scent compound in vanilla, used as a fragrance note.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.

Price · 5 oz
Usually a good value. Most stores sell it under the $15 line, and products that do this job typically go for about $21 at this size.
Sizes
The 5 oz costs 17% less per ounce than the 4 oz.
5 ozmost listedBest per ounce
4 oz
Sorted by price per ounce. Dated observations from our research, not live prices. Direct store pages, no affiliate links. We don’t sell this product.
Formula
It costs about what other heat protectants cost per ounce, but the formula leaves out film-forming heat spreader, which most of the format carries.
The formula score is completeness for the job: the share of the systems this product type is normally built around that we can find in this list, weighted. It is not efficacy, not quality, and it never compares across product types.
Does the same job
Same derived functions — what it cleans, conditions, coats or holds — at a lower cost per ounce. Scent, texture and where you buy it can still differ.

Final decision
People who blow-dry or flat-iron who want heat protection and a protein-free formula
Not ideal for anyone sensitive to fragrance, very dry or high-damage hair, or people avoiding aerosols
Nothing in our library matches it closely at a lower price.
We do not sell products or take placement fees. This page states what the formula and the prices show; the consultation is what matches it to a person.
Claims check
Claims are quoted from the brand. We only mark one supported, partly supported, or conflicting when the ingredient list actually speaks to it; everything else stays "stated by the brand", which is not a criticism — most claims simply cannot be read off a label.
